At the GRB meeting in January 2015 the Netherlands introduced a justification and proposal for future tyre noise limits (document GRB-61-03). During the discussion, it was suggested to investigate whether difference in performance existed between Original Equipment Manufacturer (OEM) tyres and replacement tyres, noting that the transitional provisions in EC/661/2009 take into account the earlier introduction of noise limits of OEM tyres mounted on new vehicle types. Therefore, the Dutch Ministry of Infrastructure and the Environment asked M+P to investigate the statistics of tyre noise label values in OEM tyres in more detail.
